I believe it would be a great feature to plot courses using items selected on system map as landmarks if at least for the final destination in plotting a course if not all the waypoints. I don't see why you should have to warp to a star all the time as a landmark. For example, if I am a miner, I could warp my ship to the planet instead of the star. This also helps with being a little more covert as well ... as people will wait by the sun to interdict you or harrass you in general and this would make them have to try a bit harder as people can come in at any celestial body within a system. Maybe even directly to a station.. but I don't know how that would effect the game in general.
